I bought the blue X, but I want the os user interface to change the color from blue to white. I have asked many after-sales service staffs, they all said it can't be changed. But I noticed that when they help the car owner to replace 20 inch wheel with 22 inch whell, they can change the pic of wheel showed on the screen, so I believe that the color can also be changed! I'm in Shanghai, China, thanks a lot to everyone!!! This question confused me for a long time.
